ESP32 Forum

Hello everyone, I want programming esp32 with java and I don't know if there is a way to do this, I have made a research but I didn't found anything. If there isn't a such thing, can anyone to point me some references/directions(/examples of portage) to do this. Thank you.

If there is java support somewhere, it's likely not to be well-supported... you may want to look into some more mainstream langues that are used more on the ESP32... C, C++ (Arduino), Javascript (NodeMCU) and MicroPython all are options.

I don't agree with you, if there is a java support that adds more options, more communities... Now I'm using C, Micropython and I don't have any problem with these language, but I wonder if anyone can point me how to let java supported for esp32 juste like Micropython.

No, I mean I do not know of any mainstream Java toolchain for the ESP32. In case I missed one that does exist, it's likely not very big, or else I would have heard about it. Just observing, I have nothing against Java communities Some Googling reveals there is something ( http://developer.microej.com/getting-st ... rover.html ) but it's a commercial SDK.

Hi all,

Secure fast Java is available on ESP32 since several years, from the company MicroEJ:

https://developer.microej.com/create-yo ... erkit-v41/
https://developer.microej.com/create-yo ... r-kit-v41/

An old Press Release from their web site announces:
+37Millions devices Powered by MicroEJ, some based on ESP32.
https://www.microej.com/press_release/c ... -standard/

Some images in the next url:

talk about "managed code" (java, javascript, etc.) ==> MicroEJ VEE sounds to be more than just Java?

And sounds like there is complete digital twin: ESP32WROVER Virtual Device, which makes it trivial to start java programming for ESP32.

Hope it helps,
Cheers
